Why Replace Your Hand Brake Valve?
A failing hand brake valve may cause slow brake release, air leakage from the dash knob, or inability to hold the truck on an incline. Replacing with a reliable MK449782 valve restores safe parking brake function.

Installation Tip:

• Always drain air tanks before removal.

• Mark air lines before disconnecting to avoid cross-connection.

• Use new sealing washers or thread sealant (non-hardening) on fittings.

• After installation, perform a full air brake system leak test and parking brake function test before returning to service.

• Torque mounting bolts to 8–12 N·m (do not overtighten the plastic knob nut).

Quality Guarantee:
Each valve is pressure-tested before shipment. No manufacturing defect for 12 months from purchase (does not cover improper installation, line blockages, or physical damage).
